Labbox pocket pH meter METRIA model M22, 1 pc.
The Labbox METRIA Model M22 pocket pH meter has been specially developed for precise and reliable measurements of pH and ORP values. It is designed for a wide range of applications in laboratories, research facilities and industrial environments and is ideal for analyzing water samples, process solutions and other liquids quickly and safely. Its robust design and extensive features give it a clear advantage over comparable products on the market, especially when above-average measurement accuracy and flexible application options are required.
Powerful functions and areas of application
The measuring device impresses with a sophisticated combination of precision and ease of use. With automatic or optional manual temperature compensation between 0 °C and 100 °C and an extended pH measuring range of -2.00 to 20.00, both everyday and special applications are covered. Thanks to the interchangeable sensor via the standardized BNC connection, the device can be flexibly adapted to different tasks. The most important technical features include:
- pH measuring range: -2.00 to 20.00
- Accuracy: ± 0.01 pH
- ORP measuring range: ± 1999 mV
- Accuracy: ± 1 mV
- Automatic or manual temperature compensation (0-100 °C)
- Three-point calibration (USA or NIST)
- Large, backlit LCD display
Up to 100 measured values can be conveniently transferred to a computer via the USB interface and graphically processed or archived if required. The display also provides information about the condition of the electrode, making it clear when it needs to be replaced or a new one purchased. Thanks to its splash-proof design and handy carrying case, the measuring device is ready for immediate use and ideal for mobile measurements. It can be powered by three 1.5 V AA batteries, so no external power supply is required when on the move.
The areas of application include:
- Quality control in the food and beverage industry, such as pH monitoring in breweries or dairies
- Regular laboratory measurements in research facilities and universities, for example when analyzing culture solutions
- Process monitoring in the chemical and pharmaceutical industries, where both pH and redox potentials need to be precisely controlled
- Environmental analysis and water management, including the measurement of surface water, waste water or drinking water samples
Thanks to the included calibration accessories (buffer solutions for pH 4.01 and 7.00), quick adjustment is possible at any time. With an additional buffer solution for pH 10.01, measurement tasks in the alkaline range can be optimally covered.
Certifications and standards
The measuring device is tailored to the common pH buffer standards according to the USA (4.01; 7.00; 10.01) and NIST (4.01; 6.86; 9.18). This guarantees standard-compliant and reproducible calibration. In addition, when used in sensitive areas, it is advisable to carry out regular comparative measurements based on applicable laboratory guidelines (e.g. DIN) in order to ensure the high measurement quality in the long term.
Concrete application examples
- Food production: When monitoring fermentation processes, such as the acidity of yoghurt or cheese, the device provides precise pH values for consistent product quality.
- Electroplating and surface treatment: In tanks and baths where metals are electrochemically deposited, precise control of pH and redox values is crucial for consistent coating results.
- Water treatment: Whether in municipal wastewater treatment plants or in industrial recycling cycles - measuring the redox voltage allows conclusions to be drawn about the efficiency of oxidation and disinfection stages. Chemicals such as chlorine, ozone or hydrogen peroxide are often used here.
- Research and development: In laboratories where prototype test series are run and results are logged synchronously, precise progress profiles can be created thanks to the storage of up to 100 data points.
Frequently asked questions (FAQ)
How often is calibration necessary
Calibration should be carried out regularly, especially before critical measurements or after long periods of inactivity. As buffer solutions for pH 4.01 and 7.00 are included in the scope of delivery, calibration is easy to carry out.
Is the device designed for mobile use?
Yes, the device has a robust housing and comes with a handy carrying case. It can be conveniently operated with three AA batteries and is therefore ideal for on-site analyses.
Can high temperatures also be measured?
The temperature sensor supplied enables measurements of up to 100 °C. This is particularly advantageous when samples are taken directly from higher temperature ranges or when hotter liquids need to be monitored in industrial processes.
Which electrode is included
The measuring device contains the METRIA PHEL-GB1-001 electrode with a maximum working temperature of 80 °C. Thanks to its BNC connection, it can be replaced by other compatible pH or redox electrodes if required.
How does the data transfer work?
Up to 100 measured values can be transferred to a PC via the integrated USB interface. This ensures simple documentation and archiving.
Conclusion
This measuring device enables precise and versatile measurements in research, industry and quality control. The wide measuring range and ease of use, coupled with a clear display and the option of memory transfer via USB, make it an extremely reliable companion for anyone who needs to monitor or analyze pH and ORP values professionally. The robust design, extensive calibration and flexible configurability round off the features and make this pH meter an excellent investment for laboratories and industrial applications.
